Product Introduction
FST700-201 Capacitance Liquid-level Transmitter  adopts a coaxial container, the capacitor consists of two coaxial electrodes: inner and outside electrodes. The capacitance  between the sensor housing (outside  electrodes) and sensoring electrodes (inside electrode) changes when the oil (liquid) is filled into the container, it output standard current, voltage, or digital signals. It can be used to testing various non-conductive liquid.
